Jean Delvare 0314b020c4 ds2482: Discard obsolete detect method
There is no point in implementing a detect callback for the DS2482, as
this device can't be detected. It was there solely to handle "force"
module parameters to instantiate devices, but now we have a better sysfs
interface that can do the same.

So we can get rid of the ugly module parameters and the detect callback.
This shrinks the binary module size by 21%.

Description
-----------
The Maxim/Dallas Semiconductor DS2482 is a I2C device that provides
one (DS2482-100) or eight (DS2482-800) 1-wire busses.
General Remarks
---------------
Valid addresses are 0x18, 0x19, 0x1a, and 0x1b.
However, the device cannot be detected without writing to the i2c bus, so no
detection is done. You should instantiate the device explicitly.
$ modprobe ds2482
$ echo ds2482 0x18 > /sys/bus/i2c/devices/i2c-0/new_device
